【考案の詳細な説明】
本考案は合成繊維又はその製品等の連続物の製造工程に
おいて延伸、収縮、染色等の熱処理を行うため、ラビリ
ンスシールを備えた連続熱処理装置のラビリンスシール
部における熱歪を防止するための改良に関するものであ
る。[Detailed description of the invention] The present invention is designed to apply thermal stress in the labyrinth seal part of a continuous heat treatment equipment equipped with a labyrinth seal in order to carry out heat treatments such as stretching, shrinkage, and dyeing in the manufacturing process of continuous products such as synthetic fibers or their products. This relates to improvements to prevent this.
従来一般にラビリンスシールを備えた連続熱処理装置の
ラビリンスシール部は漏洩量を小さく押えるために歯と
歯との間隙をできるだけ小さく保つ必要がある。Conventionally, in the labyrinth seal section of a continuous heat treatment apparatus equipped with a labyrinth seal, it is necessary to keep the gap between the teeth as small as possible in order to suppress the amount of leakage.
ところがこの装置に熱が加わると必然的に各部に温度差
が生じ、その結果熱歪が惹起される。However, when heat is applied to this device, temperature differences inevitably occur in various parts, resulting in thermal distortion.
そのためラビリンスの歯と歯との間隙は一定とならず、
中央部に比して両端部の間隙が大きくなる。Therefore, the gap between the labyrinth teeth is not constant,
The gap between both ends is larger than that at the center.
又一方処理物を円滑に通過させるためには最小限必要な
間隙を確保する必要がある。On the other hand, in order to allow the processed material to pass through smoothly, it is necessary to ensure a minimum necessary gap.
そのためラビリンスの歯と歯との間隙はラビリンス全幅
を考えた場合、平均的に増大することになり、漏洩量が
増大する。Therefore, the gap between the teeth of the labyrinth increases on average when considering the entire width of the labyrinth, and the amount of leakage increases.
更にこの熱歪の程度は処理温度が高くなるほど、又装置

歯と歯との間隙が不均一になるだけに留らず、処理物の
円滑な通過が妨げられ、ラビリンスの歯と処理物との間
に好ましくない摩擦が生じ、処理物を損傷せしめること
にな、又上下ラビリンスプレートの側面の合せ目のシー
ル部から熱媒が漏洩する欠点がある。Furthermore, the degree of thermal distortion increases as the processing temperature rises and as the equipment becomes larger, and as a result, not only does the gap between the teeth of the labyrinth become uneven, but it also affects the smoothness of the processed material. Passage is obstructed, causing undesirable friction between the teeth of the labyrinth and the object to be processed, which may damage the object to be processed.Also, there is the disadvantage that the heat medium leaks from the seal at the joint between the sides of the upper and lower labyrinth plates. be.
従来のラビリンスシールを持った連続熱処理装置はラビ
リンスシールの幅が高々５〇−程度であり、熱媒も蒸気
で温度１３０℃、圧力３ｋｙ／ａｆｔＧ程度のものであ
った。In the conventional continuous heat treatment apparatus having a labyrinth seal, the width of the labyrinth seal is at most about 50 mm, and the heating medium is steam at a temperature of 130 DEG C. and a pressure of about 3 ky/aftG.
この程度の使用条件においては設計的には熱歪に関して
ごく通常の考慮を払うだけで充分である、例えば熱膨張
による寸法変化のみを考慮してその逃げの空間を確保し
ておく程度で実用上差支えなかった。Under these conditions of use, it is sufficient to take ordinary considerations into consideration regarding thermal distortion. For example, in practice, it is sufficient to take only dimensional changes due to thermal expansion into account and ensure a space for relief. It didn't matter.
ところが温度が１５０℃、圧カフに９／ｃＪＧ程度にな
り、シール幅が１ｒｒＬ程度にもなると上記の欠点が生
ずるようになる。However, when the temperature is 150° C., the pressure cuff is about 9/cJG, and the seal width is about 1rrL, the above-mentioned drawbacks occur.
本発明は上記従来の欠点を除去し、高温及び大型におけ

置においても円滑−な運転を可能にし、且つ熱媒の漏洩
量をラビリンスシールとして理想的な最小値とすること
を目的とするものである。The present invention eliminates the above-mentioned conventional drawbacks, minimizes thermal distortion of the labyrinth seal portion of a continuous heat treatment equipment having a labyrinth seal at high temperatures and large sizes, and enables smooth operation even in high temperature and/or large-sized equipment. , and the purpose is to reduce the leakage amount of the heating medium to an ideal minimum value as a labyrinth seal.
次に本考案を図面によって詳細説明する。Next, the present invention will be explained in detail with reference to the drawings.

みが１悶以下の場合が多いから、ｌ〜５ＴＩＩ！ＩＬ程
度、通常は２〜３ｒＩｒ！ｎに設定する場合が多い。FIG. 1 is a schematic side sectional view of an embodiment of the present invention, in which labyrinth seals 2 and 2' are provided at both ends of a processing tube 1, and a high temperature and high pressure heating medium is introduced into the processing tube 1, where fibers or Continuous objects such as textile products are heat treated, and the gap 3 between the labyrinth teeth of the labyrinth seal parts 2 and 2' depends on the thickness of the object to be treated, but in the case of fibers or cloth-like objects, the gap 3 between the teeth of the labyrinth seals 2, 2' The thickness is often less than 1 inch, so it is 1 to 5 TII! About IL, usually 2-3rIr! It is often set to n.
この間隙はそのラビリンスシール部の全幅に互って常に
均一に保つことが処理物の円滑な運転上必要である。It is necessary to keep this gap uniform throughout the entire width of the labyrinth seal portion for smooth operation of the processed product.
この間隙を均一に保つためには各部材の各部の温度が均
一になることを必要とするが、現実には高温の熱媒がラ

本考案はこの熱歪を防止するためにハウジング４．４′
とラビリンスシール部２．２’のプレートの間を断熱し
、ラビリンスプレートの厚みを充分薄くして剛性を減ら
し、一方ハウジング４，４′は充分厚くして剛性を大き
くする。In order to keep this gap uniform, it is necessary that the temperature of each part of each member be uniform, but in reality, a high temperature heat medium passes through the inside of the labyrinth seal, and there is a large temperature difference between it and the outside temperature. If there is a temperature difference between the inside and outside of each member, it is a normal phenomenon that thermal distortion occurs due to this.In order to prevent this thermal distortion, the present invention has a housing 4.4'.
and the plates of the labyrinth seal 2.2', the thickness of the labyrinth plates is made sufficiently thin to reduce stiffness, while the housings 4, 4' are made sufficiently thick to increase stiffness.
かくすればハウジング４，４′の内外の温度差は極く小
さくなる。In this way, the temperature difference between the inside and outside of the housings 4, 4' becomes extremely small.
従って温度差による歪は殆んど生じない。Therefore, almost no distortion occurs due to temperature differences.
一方ラビリンスシール部のプレート２，２′は内外に温

びその平面の直線を維持する必要がある。In this case, since the temperatures of the housings 4, 4' and the plates 2, 2' of the labyrinth seal section are different, there will be a difference in length between them due to the difference in thermal expansion. Although the mating surfaces of the fibers are brought into close contact with each other, it is necessary to maintain the flow direction of the fibers or textile products and the straight line of the plane shown by the arrows in FIG.

である。The width of the air layers 5, 5' varies somewhat depending on the type of continuous heat treatment equipment, but the width of the air layers 5, 5' differs slightly depending on the type of continuous heat treatment equipment. In order to fix the labyrinth seal portion 2, which has low rigidity, to the housing 4, a fit-in type 9 is used instead of the bolt 8 shown in FIG.
ハウジング４はその外面が室内大気に接し、その内面が
室内大気に通じでおり、対流が起らないような距離とし

よってラビリンスの歯７とこれに対向して配置されたラ
ビリンスの歯７′との間隙が一定に保たれるのである。Furthermore, the thermal strain caused by the temperature difference is corrected by the bolt 8 or the fit-in method 9, so that the gap between the teeth 7 of the labyrinth and the teeth 7' of the labyrinth placed opposite thereto is kept constant by these actions. It is preserved.

れが防止でき、円滑な運転が可能になる利点がある。The present invention insulates the space between the housing 4 and the labyrinth plate 2 with an air layer, further provides a heat insulating material layer in close contact with the labyrinth seal part in the air layer, and allows outside air to flow through the air layer. Since the gap between the teeth (7) and the teeth (7) of the labyrinth arranged opposite to the teeth 7 is kept constant, the amount of leakage is kept to a minimum, which is ideal for a labyrinth seal, and damage to continuous fibers or textile products can be prevented. Furthermore, since the thermal distortion of the housing can be minimized, leakage from the side surfaces of the labyrinth seal can be prevented and smooth operation can be achieved.
